Majority of earthquakes occur at transform boundaries. what sphere is responsible for the sudden jump of the earth's crust?

A. hydrosphere because the weight of moving water causes the rock to crack

B. biosphere because humans mine into mountains causing the rock to crack

C. cryosphere because as the ice melts it cracks through the ice and into the rock

D. geosphere because the rock is sliding past each other

D

Explanation:

As tectonic plates of the earth slide past each other, they send off giant vibrations which are earthquakes.

D. geosphere because the rock is sliding past each other

Explanation:

Transform plate boundary has two plates slip past each other in the opposite direction without any collision. Transform plate boundary prone to many occurrences of earthquakes, which will neither creates nor destroys any crust in these boundary areas, it is otherwise known as conservative plate boundary, where faults and folds were occurred. San Andreas fault of western North America and Alpine fault of New Zealand are the examples of conservative plate margin.
